I'm pretty sure lightdm depends on logind, but not systemd but I could
be wrong. Did you try installing elogind as a replacement?

systemd can run very well on memory-constrained systems if you take the
time to configure it. It enables a lot of services and features by default
that you can just disable.

I don't think this is reasonably possible except for very simple service
files. The problem is that SysVInit uses bash scripts while systemd uses
a declarative format which doesn't contain any executable code.

You should be able to enable old ciphers and algorithms on the SSH command
line to be able to connect to a server using an older version of the SSH
server.
